TAILIEUCHUNG - Different growth performance - tilapia (oreochromis niloticus) in using two different types of feed at hoa my reservoir, Thua Thien Hue province, Vietnam

Objective find the effect of different protein level: industrial feed (35% protein) and blended feed (21% protein) on growth performance, survival rate parameters of fish. The fingerlings were stocked in four cages ( meter each), surrounded by fishing net. | BÀI BÁO KHOA HỌC DIFFERENT GROWTH PERFORMANCE - TILAPIA (OREOCHROMIS NILOTICUS) IN USING TWO DIFFERENT TYPES OF FEED AT HOA MY RESERVOIR, THUA THIEN HUE PROVINCE, VIETNAM Luong Quang Tuong1, Nguyen Phi Nam1 Abstract: Aquaculture is a kind of method for utilizing the potential of available water areas such as at Hoa My reservoir. The Tilapia (Oreochromis niloticus) with average weight of g is a candidate for developing aquacultural activities. Objective find the effect of different protein level: industrial feed (35% protein) and blended feed (21% protein) on growth performance, survival rate parameters of fish. The fingerlings were stocked in four cages ( meter each), surrounded by fishing net. The temperature, pH and DO parameters were recorded 2 times per day at 7am and 2pm, being calculated as an average value at 7 days interval. Growth measurements of Tilapia relating to the weight and length of fish were recorded at 15 days intervals. The findings show that Hoa My reservoir seems a potential with stability of pH () and DO ( mg/). The survival rate (SR) in the blended feed is 89,7% and the industrial feed is 94,7%. The feed conversion ratio (FCR) of fish fed by blended feed and industrial feed is and , respectively. It means that the industrial feed had higher economic efficiency , compared with the blended feed in same environmental conditions. Keywords: reservoir; Tilapia; water parameters; nutrition; economic efficiency. 1. INTRODUCTION1 Aquaculture seems as the fastest growing food-production sector in the world. Aquaculture contributes to the economy and has the potential for mitigating environmental impacts (Silva and Soto 2009) because of the advantage of fish characteristic, requiring less than 2 kilograms of feed for providing each kg product. This characteristic show the most efficiently producing aquatic animals in terms of the feeds - associated with the amount of water use (Verdegem, Bosma, and .
